- Buy only from the brand or an authorised dealer.

- Test the inverter, display and Wi-Fi app at installation.
Pakistan’s solar market has grown very fast. That is good news for buyers, but it also means more fake, copied and refurbished inverters being sold as new. A fake inverter can fail early, damage your batteries and leave you with no warranty. These simple checks protect you.
7 checks before you buy a solar inverter
1. Buy from the brand or an authorised dealer
Ask the seller if they are an authorised dealer. For Infinix products, you can confirm directly with Infinix Solar on 0321-0911151.
2. Check the serial number
The serial number on the inverter label should match the box and the warranty card. Missing, scratched or mismatched serials are a red flag.
3. Get a proper invoice and warranty card
Always get a written invoice with the model, serial number, date and seller details, plus the warranty card. Without them, warranty claims are difficult.
4. Watch out for prices that are too low
If a price is far below what others charge, ask why. Very cheap “new” inverters may be refurbished, old stock or copies.
5. Inspect the box and the unit
Look for proper branding, sealed packaging, a clean body and a correct label. Scratches, loose screws or dust inside the box can mean a used unit.
6. Test at installation
Check that the display works, the inverter charges the battery, and the Wi-Fi or app monitoring connects. Ask the installer to show you the settings.
7. Know who will give after-sales support
Before paying, ask who handles warranty and technical support, and get a contact number.

Signs you may have a fake or used inverter

- No invoice or warranty card offered.
- The seller cannot explain where it came from.
- The unit looks worn, or the display shows high running hours.
- The app or Wi-Fi monitoring does not work as advertised.
